The carotenes α-carotene, β-carotene, γ-carotene, and the xanthophyll β-cryptoxanthin, can all be metabolized to β-ionone, and thus have vitamin A activity because they can be converted by plant-eating animals to retinol and retinal. Individuals who contain at least one G allele are sensitive to beta-ionone and perceive a pleasant floral scent, while individuals who are homozygous AA are ~100 times less sensitive and at higher concentrations perceive a pungent sour/vinegar odor instead. ... Monoisotopic Mass: 192.151415 g/mol: Computed by PubChem 2.1 (PubChem release 2019.06.18) CAS 8013-90-9, molar mass 192.3 g/mol. The ionones are a series of closely related chemical substances that are part of a group of compounds known as rose ketones, which also includes damascones and damascenones. Ionones are aroma compounds found in a variety of essential oils, including rose oil. It will calculate the total mass along with the elemental composition and mass of each element in the compound. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). A single-nucleotide polymorphism in the OR5A1 receptor (rs6591536[7]) causes very significant differences in the odor perception of beta-ionone, both in sensitivity and also in subjective quality.
Ionone C13H20O Molar Mass, Molecular Weight. Molar Mass: 192.2973 :: Chemistry Applications:: [4], Ionone can be synthesised from citral and acetone with calcium oxide as a basic heterogeneous catalyst and serves as an example of an aldol condensation followed by a rearrangement reaction.[5][6]. Definitions of molecular mass, molecular weight, molar mass and molar weight. Examples: Fe, Au, Co, Br, C, O, N, F. You can use parenthesis or brackets []. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. Calculate the molecular weight molar mass and molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. These are monoterpenes that do not contain a cycle. IDENTIFICATION: beta-Ionone is a colorless to pale, straw-colored liquid. Molarity (concentration) = moles of solute / liters of solution. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes.
